Purpose and fit

This bidirectional SFP transceiver delivers 1.25 Gbps over single-mode fibre at distances up to 20 km. It uses a 1310 nm transmitter and 1550 nm receiver with a simplex LC connector, making it suitable for Gigabit Ethernet 1000BASE-BX10-U and 1 Gbps Fibre Channel links in enterprise and campus networks.

Sustained-load behaviour

The module operates from 0 °C to 70 °C on a single 3.3 V supply and complies with the INF-8074i SFP MSA and SFF-8472 diagnostics interface. Hot-pluggable design allows insertion or removal without powering down the switch, while RoHS-compliant construction meets environmental requirements for continuous deployment.

Pre-order checks

Verify that your switch or router port supports 1000BASE-BX-U optics and accepts the Tx1310 nm / Rx1550 nm wavelength pairing; the opposite end must use the complementary Tx1550 nm / Rx1310 nm module. Confirm the host equipment brand and model so the correct vendor coding can be programmed before shipment. Ensure single-mode patch cables with LC simplex connectors are available for the link.

Questions about this item

How much heat does the 1310nm FP laser transmitter generate during continuous 1.25Gbps operation?

The module runs on a single 3.3V supply and is rated for 0°C to 70°C commercial temperature, so it stays within normal switch airflow limits during extended use.

What existing switch port and fiber type are required to use this Tx1310nm/Rx1550nm transceiver?

You need an SFP MSA compliant slot supporting 1000BASE-BX-U and a simplex LC single-mode fiber patch cable to complete the link.

Will this 20km BIDI module work in a legacy switch that only lists IEEE 802.3ah 1000BASE-BX10-U support?

Yes, it is compliant with IEEE 802.3ah 1000BASE-BX10-U and INF-8074i SFP MSA, so it interoperates with older Gigabit Ethernet ports that follow those standards.
